Slack SSO Login into Drupal OAuth Client using OAuth / OpenID connect
Overview
Drupal Slack SSO integration will allow the users to log in to the Drupal site using the Slack Credentials.
This SSO integration is achieved by the miniOrange OAuth Client module which uses the OAuth 2.0 and OpenID
Connect (OIDC) Protocol.
In this document, we will help you to configure the single Sign-on login using the OAuth protocol between the
Drupal site and the Slack.
Installation Steps
- Using Composer
- Using Drush
- Manual Installation
Configuration Steps
Setup Drupal as OAuth Client:
- After installing the module, navigate to the Configuration → miniOrange OAuth Client Configuration → Configure OAuth tab and select Slack from the Select Application dropdown list.
- Copy the Callback/Redirect URL and keep it handy.
- In the Display Name text field, enter the name of the application. For example, Slack.
Note: If your provider only supports HTTPS Callback/Redirect URLs and you have an HTTP site, please make sure to enable the 'Enforce HTTPS Callback URL' checkbox at the bottom of the tab.
Configure SSO Application in Slack:
- Go to Slack and login to your Slack account.
- Click on Create an App button.
- Select the option From Scratch.
- Enter App name and Development Slack Workshop. App name can be anything and by default Slack Workshop is Group but you can sign in to another workspace. Click on the Create App button.
- Navigate to OAuth & Permissions from the left navigation panel.
- Scroll down to find the Redirect URLs section. Click on Add Redirect URL. Paste the previously copied the Callback/Redirect URL from Drupal into the Redirect URLs text field then click on Add button.
- Click on the Save URLs button to save the Redirect URL.
- Then, scroll Down to Scopes section and add necessary scopes. Most importantly, these scopes must be the same on the miniOrange OAuth Client module configuration page.
- Navigate to the Basic Information tab from left side menu.
- Scroll down to App Credentials section and copy the Client ID. Then, click on Show button and copy the Client Secret. Keep it handy.
Integrating Drupal with Slack:
- Go to miniOrange OAuth Client module.
- In Drupal’s Configure OAuth tab and paste the copied Client ID and Client Secret from Slack in the Client ID and Client Secret text-field.
- Confirm the Scope & Endpoints and then click on Save Configuration button.
| Scope | users.profile:read |
|---|---|
| Authorize EndPoint | https://slack.com/oauth/authorize |
| Access Token Endpoint | https://slack.com/api/oauth.access |
| Get User Info Endpoint | https://slack.com/api/users.profile.get |
Test Connection between Drupal and Slack:
- After successfully saving the configurations, please click on the Test Configuration button to test the connection between Drupal and Slack.
- On a Test Configuration popup, if you don't have any active sessions on the same browser, you will be requested to login into the Slack. After successfully logging into the Slack, you will be provided a list of attributes received from the Slack.
- Select the Email Attribute from the dropdown menu in which the user's email ID is obtained and click on the Done button.
Note: Mapping the Email Attribute is mandatory for your login to Slack.
- On the Attribute & Role Mapping tab, please select the Username Attribute from the dropdown list and click on the Save Configuration button.
- Now log out and go to your Drupal site’s login page. You will automatically find a Login with Slack link there. If you want to add the SSO link to other pages as well, please follow the steps given in the image below:
Congratulations! You have successfully configured Slack as OAuth/OpenID Provider and Drupal as an OAuth Client.

After I click on the logout in Drupal, it sends me back to
the Drupal homepage. However, when I try to login with other user, it doesn't ask me to login but
automatically logs me in with same user
The logout functionality you've mentioned here is the default behavior of a module. It's logging you out of Drupal but not from your Application/Provider. To allow the module to logout from your provider/application account (what you are looking for), you need to make the below configurations: [know more]
I purchased the paid Drupal module and replaced it with
the free module, but still I am not able to use paid features.
As you have upgraded to one of our paid versions of the Drupal module and replaced the free module with the paid one, you must first activate the paid module. Please refer to the below steps. [Know more]
